The first extension board and the second extension board are turnable between a closed position where the first and second extension boards overlap a top surface of the top board and an open position where the first and second extension boards are opened sideways respectively from left and right sides of the top board. The top surface of the top board and top surfaces of the first extension board and the second extension board are arranged on a same plane.

TECHNICAL FIELD

The present invention relates to a cabinet for office work suitable foruse to store various kinds of articles such as documents and lay alaptop or tablet type computer thereon, and specifically relates to acabinet suitable for use in a consultation room of a hospital and adental clinic.

BACKGROUND ART

Conventionally, there is a cabinet for office work used to store variouskinds of articles such as documents, for example, as disclosed in PatentDocuments 1 and 2. This kind of cabinet is formed in a box shape as awhole, including storable drawers inside and a top board on which thearticles can be laid. In addition, casters attached on a bottom surfaceenables easy displacement of the cabinet without lifting.

When in use, on one hand, if the above-described cabinet has a wider topboard for laying the articles, the usability of the cabinet improves asmore documents can be laid thereon. When not in use, on the other hand,the smaller an outer width dimension and overall depth of the cabinetis, the more suitable the cabinet is as the cabinet never needs tooccupy larger space.

Further, the above-described cabinet may be used in a consultation roomof medical institutions such as a hospital and a dental clinic. In thiscase, the cabinet is used also for laying and operating a laptop ortablet type computer and a mouse thereon other than for storingdocuments such as medical charts. Under such circumstances, it isdesirable from the hygienic point of view to store the articles in anisolated place in the consultation room except for the case of usingthis tablet type and other computer, etc. so that no liquid spray easilysplashes thereover.

Therefore, in the conventional cabinet, these tablet type and othercomputers, etc. stored in the drawer when not in use need to be takenout from the drawer and then laid on the top board of the cabinet whenin use. However, it is annoying and inefficient to take in and out thecomputer from the drawer each time when in use.
